Resumo

Barbiturates induce CYP3A4 and can substantially lower doravirine concentrations. This risks loss of virologic suppression and development of resistance. Doravirine labeling advises against strong CYP3A inducers.

O que esta interação significa em palavras simples

Amobarbital and Doravirine are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.

Amobarbital belongs to Central Nervous System; Doravirine belongs to Anti Virals.

Nível de evidência: Moderate

Por que acontece

Barbiturate-mediated CYP3A4 induction increases doravirine metabolism.

O que fazer

Avoid the combination and use a non-inducing sedative. If an inducer is unavoidable, use an alternative antiretroviral regimen.
